Shine bright like a rockstar ... or a runner who wants to be seen by drivers (basically the same thing). With fabric that both insulates and breathes, you won't overheat in these cool-weather converge leggings that shine after dark. With 3M™ Scotchlite™ Carbon Black Stretch reflectivity in critical motion zones, drivers and pedestrians alike will be able to see you as a runner in motion. Plus, the envelope pocket at the center is large enough for your phone. Time to get running!
